Mbh 6.104.1a

Sanjaya said, “At mid-day, O king, happened a fierce battle, fraught with great carnage, between Bhishma and the Somakas. That foremost of car-warriors, viz., Ganga’s son began to consume the ranks of the Pandavas with keen shafts by hundreds and thousands. Thy sire Devavrata began to grind those troops like a herd of bulls grinding (with their tread) a heap of paddy sheaves. Then Dhrishtadyumna and Sikhandin and Virata and Drupada, falling upon Bhishma in that battle, struck that mighty car-warrior with numerous arrows. Bhishma then, having pierced Dhrishtadyumna and Virata each with three arrows, sped a long shaft, O Bharata, at Drupada. Thus pierced in battle by Bhishma, that grinder of foes, those great bowmen became filled with wrath, O king, like snakes trod upon (by human feet). Then Sikhandin pierced the grandsire of the Bharatas (with many shafts). Of unfading glory, Bhishma, however, regarding his foe as a female struck him not. Dhrishtadyumna then, in that battle, blazing up with wrath like fire, struck the grandsire with three shafts in his arms and chest. And Drupada pierced Bhishma with five and twenty shafts, and Virata pierced him with ten, and Sikhandin with five and twenty. Deeply pierced (with those shafts) he became covered with blood, and looked beautiful like a red Asoka variegated with flowers. Then the son of Ganga pierced, in return, each of them with three straight shafts. And then, O sire, he cut off Drupada’s bow with a broad-headed arrow. The latter then, taking up another bow, pierced Bhishma with five shafts. And he pierced Bhishma’s charioteer also with three sharp shafts on the field of battle. Then the five sons of Draupadi, and the five Kaikeya brothers and Satyaki also of the Satwata race, headed by Yudhishthira, all rushed towards Ganga’s son, desirous of protecting the Panchalas headed by Dhrishtadyumna.
